UTM parameters are the little tags, utm_source, utm_medium, utm_campaign, you append to a URL so Google Analytics can tell you exactly which email, ad, or social post drove each visit. Without them, all your campaign traffic blurs together. Our free UTM Link Builder formats those tracked URLs perfectly, every time.
Enter your destination URL plus the source, medium, and campaign name, and the tool assembles a clean, correctly encoded link you can paste into newsletters, ads, and social posts.
Confused by the parameters? Our UTM parameters explained guide walks through each one with examples.
